need help diagnosing

I have new parts en route for an ear shave procedure but until then I have other issues to tend to.

my bike is still stuttering like crazy and this weekend I was going to clean the carbs again so I disconnected all the hoses and Boots. I ran out of daylight yesterday and decided to do it later so I reconnected everything this morning and headed to work.

bike ran like a dream for 10 miles and then started stuttering again.

only other thing I did to the bike was add more coolant and play with the slides in the carbs a little bit they slid just fine.

last weekend I cleaned out the tank and petcock but the problem was still there.

what is the deal with this horrible stuttering?

ten miles and then it messes up how were you riding and did it clear up or not it could be many things

is the battery good do you have your carb vent tube in a good position?

Garage
Could be as simple as bad gas, carb vent tube not routed properly, or possibly a grounding issue. I had a stator, when it was warm only, start to ground out and it would affect ignition.

It stutters under any kind of load. Idle seems fine. During the 10 miles it was handling any load no problems. I think I'm gonna toggle the slides again and see if the stuttering stops again.

The carb vent tube. Is that the one that has to goto dead air? If so I have that cut at a 45 degree angle so it cant get closed off and it is routed to that slot on the back of the right ear

yeah thats the tube in question you did right by cutting the 45 and tucking it in the ear but make sure it isnt pinched up anywhere

also check your gas cap for clogs and your tank vent if you have one
